INSTALLATION AND USE

VSP2 is a pre-assembled system intended for connecting
to water mains or a primary collection tank. It provides
water supply and pressurization and is ideal for residential,
commercial, and public buildings. It’s also suitable for
hotels, park irrigation, as well as industrial water handling
and treatment.
VSP2 is compatible with clean water and aqueous solutions
that do not chemically or mechanically harm the
materials used and are free from abrasive or fibrous substances.

PRODUCT DESCRIPTION

VSP2 is a pressurization system comprising two pumping
units connected in parallel. Integrated inverter devices
automatically adjust their operation to varying water demands
while ensuring constant pressure.
When system pressure drops due to water withdrawal, the
first VSP unit starts working to provide the necessary water
flow rate, maintaining pressure. Once the maximum rotation
speed is reached, the second VSP unit starts to fulfill
the system’s water demand.

COMPONENTS

※ TWO VSP PUMPING UNITS connected in parallel via
suction and discharge manifolds. Each unit is equipped
with ball valves on the supply and suction side, non-return
valves on the suction side (FCR, PLURIJET, MK) or on
the supply side (HT-PRO). The electronics integrated in
VSP can manage the alternating operation of individual
units.

VSP2 is designed to protect the system from:

※ dry running
※ overvoltage and under voltage
※ combustion chamber
※ BASE made of metal profile and equipped with adjustable
vibration-damping feet.
※ PRESSURE TRANSDUCER (4-20mA) installed on the
supply manifold, which enables command and control
of the pressurization unit.
※ ELECTRICAL PANEL with thermal-magnetic circuit
breakers for three-phase versions and thermal-magnetic
circuit breakers for single-phase versions.

VSP2 – FCR
Pressurization units comprise two multistage centrifugal pumps with an integrated
inverter in the motor, capable of maintaining constant pressure in the system.
They are used for water supply in residential, commercial, and public buildings, as
well as for garden irrigation and general clean water movement.

TECHNICAL DATA
• Liquid temperature between -10 °C and +60 °C
• Ambient temperature between -5 °C and +40 °C
• Max. pressure in the pump body 10 bar
• Continuous running duty S1

VSP2 – PLURIJET
Pressurization units comprise two self-priming multistage centrifugal pumps with
an integrated inverter in the motor, capable of maintaining a constant pressure in
the system. They are utilized for water supply, including from underground reservoirs,
in residential, commercial, and public buildings, as well as for garden irrigation
and general clean water movement.

TECHNICAL DATA
• Liquid temperature between -10 °C and +40 °C
• Ambient temperature between -5 °C and +40 °C
• Max. pressure in the pump body 10 bar
• Continuous running duty S1

VSP2 – MK
Pressurization units comprise two vertical multistage pumps with an integrated
inverter in the motor, capable of maintaining a constant pressure in the system.
They are used for water supply in residential, commercial, and public buildings, as
well as for handling clean water.

TECHNICAL DATA
• Liquid temperature between -10 °C and +60 °C
• Ambient temperature between -5 °C and +40 °C
• Max. pressure in pump body 11 bar
• Continuous running duty S1

VSP2 – HT PRO
Pressurization units comprise two vertical multistage pumps with integrated inverters
in the motor to maintain consistent pressure in the system. They’re commonly
used for water supply in commercial and public buildings, irrigation in parks
and athletic fields, and for industrial water treatment.

TECHNICAL DATA
• Liquid temperature between -10 °C and +60 °C
• Ambient temperature between -5 °C and +40 °C
• Max. pressure in pump body 11 bar
• Continuous running duty S1
